A review on the applications of type-2 fuzzy logic in classification and pattern recognition

• A review of type-2 fuzzy logic applications in pattern recognition and classification problems is presented.
• Type-2 fuzzy logic has gained popularity in a wide range of applications.
• A representative review of the most successful applications of type-2 fuzzy logic in these fields is presented.

In this paper a review of type-2 fuzzy logic applications in pattern recognition, classification and clustering problems is presented. Recently, type-2 fuzzy logic has gained popularity in a wide range of applications due to its ability to handle higher degrees of uncertainty. In particular, there have been recent applications of type-2 fuzzy logic in the fields of pattern recognition, classification and clustering, where it has helped improving results over type-1 fuzzy logic. In this paper a concise and representative review of the most successful applications of type-2 fuzzy logic in these fields is presented.
